The selected candidate will support the design and optimization of fluid, gas, humidity, and thermal management systems for advanced low-temperature hydrogen fuel cell applications, including systems requiring the concurrent operation of multiple fuel cell stacks.

Key Responsibilities

Design, develop, and optimize balance of plant systems for PEM hydrogen fuel cell applications. Support the design of hydrogen gas distribution systems, air delivery systems, humidification systems, cooling loops, piping, manifolds, pumps, valves, compressors, sensors, and related BoP components. Apply fluid dynamics and hydrodynamics principles to control and optimize air flow rate, air pressure, hydrogen delivery, water management, and absolute humidity supplied to the fuel cell.

Perform fluid flow analysis, pressure drop calculations, thermal-fluid evaluations, and system-level performance optimization.

Support scaling of gas delivery and air management systems for higher power levels, including architectures requiring the simultaneous operation of multiple fuel cell stacks. Evaluate and improve fuel cell cooling systems, humidification strategies, reactant delivery, and thermal management performance. Work closely with engineering, product development, testing, and manufacturing teams to ensure designs are practical, reliable, safe, and scalable. Support prototype development, testing, validation, troubleshooting, and design iterations. Contribute to technical documentation, design reviews, engineering specifications, and system architecture decisions.

Required Qualifications

Minimum 3 years of professional experience in fuel cell balance of plant systems, fluid dynamics, hydrodynamics, or thermal-fluid system design.

Experience with PEM fuel cells, low-temperature hydrogen fuel cell systems, or related electrochemical energy systems.

Hands-on experience with fuel cell gas delivery BoP systems, including hydrogen gas distribution, air distribution, humidity control, and cooling systems.

Strong knowledge of fluid dynamics, including laminar and turbulent flow, pressure management, flow control, and humid air behavior. Ability to control and optimize air flow rate, air pressure, and absolute humidity in fuel cell reactant delivery systems. Understanding of thermodynamics, heat and mass transfer, transport phenomena, and system-level thermal-fluid design. Ability to translate theoretical fluid mechanics knowledge into practical engineering design for real-world fuel cell systems.

Graduate degree preferred in Mechanical Engineering, Chemical Engineering, Aerospace Engineering, Fluid Mechanics, or a related discipline.

Preferred Qualifications

Experience scaling fuel cell gas systems for higher power applications and multi-stack PEMFC operation.

Knowledge of PEMFC bipolar plate design and its relationship to reactant distribution, water management, pressure drop, and system performance. CFD or fluid simulation experience. Experience with pumps, valves, sensors, compressors, humidifiers, heat exchangers, cooling loops, and hydrogen system components.

Familiarity with CAD, system modeling, engineering analysis tools, and test validation methods. Knowledge of hydrogen safety practices and system design standards. Strong problem-solving ability and effective cross-functional communication skills Master’s degree or PhD with studies focused on fluid mechanics, including laminar and turbulent flow of humid air. Experience with thermodynamics, heat and mass transfer, electrochemistry, transport phenomena, and porous media flow.
